Total lung capacity is defined as the sum of all the lung volumes, including tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume.

Answer: B 
 Inspiratory capacity is defined as the maximum amount of air that can be inhaled after a normal tidal volume expiration. It is calculated as the sum of tidal volume and inspiratory reserve volume.

Answer: C 
 Vital capacity is defined as the maximum amount of air that can be exhaled after a maximum inhalation. It is calculated by adding together inspiratory reserve volume, tidal volume, and expiratory reserve volume.

Answer: D 
 Functional residual capacity is defined as the amount of air remaining in the lungs after a normal exhalation. It is calculated by adding together expiratory reserve volume and residual volume.
